I have a requirement from another company to encrypt/decrypt files via gpg (files are then FTP'ed). I am having problems getting a key generated (using CentOS 6.3, if that matters).

I am using "gpg --gen-key", and I get the following errors:

gpg --gen-key
can't connect to `/home/bob/.gnupg/S.gpg-agent': No such file or directory
gpg-agent[25596]: command get_passphrase failed: Operation cancelled
gpg: cancelled by user
gpg: Key generation canceled.

I have tried starting the agent (both as the "bob" use and as "root"), but I still get the same error. I have tried running "gpg-agent --verbose --server" and I do not see any errors from the agent.

Any help would be greatly appreciated.

Thanks, but unfortunately that did not resolve my issue (and the first link seems woefully out of date - IE: menu items for "gpg --gen-key" don't even match the menu items of the current version - seems to be docs for version 1.0 not 2.0). Second link seems to be for current docs, but I get the same errors when following these directions.
